I drove through one the first time and got thrown off slightly (and I'm from MA, the land of rotaries/traffic circles/random lane drops/old layouts). But, just follow the signs and one should be fine. The roads are overengineered in the turns to force people to see that clearly they should continue in a forward direction without turning (for those wishing to continue "straight through" from one side to another).
